Parental care is taken as all the provisions made by parents for their young, but why does the extent of parental care vary so widely between species, and what are the evolutionary implications of the degree of care? These and many other questions are addressed in this book. Subjects covered include variation in egg size, viviparity and other forms of bearing, differences in duration of incubation, gestation and lactation, uni/biparental care, and benefits/costs to both sexes. A comprehensive review of current knowledge.
